This is such a bullshit, biased article. Sonys own press conference confirmed as much for their own console. Not to mention that ssd's alone allow for smaller file sizes as data doesnt have to be replicated throughout for faster access. Next the ps5 has a higher raw data throughput. Once you factor in its decompression capabilities it has vastly superior IO capabilities than the XSX.
It's true every website seems to be biased towards Microsoft.
Do some research, Sony are using there own take on kraken. Sony also has way better IO compared to Microsoft.
Xbox have 12.1 Tf advantage and the memory bandwidth. The rest is Sony or the same.
